IMPROVEMENT IN FOUNTAlN-PENS.

Specification forming part of Letters Patent N 0. 184,754, dated November 28, 1876 application filed October 23, 1876.

- tudinal section.

My invention relates to an improved fountain-pen holder, in which anordinary pen-nib may be used.

The invention consists in controlling the flow of ink to the nib byadmitting the air to replace the ink in the reservoir through a bentU-shaped capillary tube leading from an orifice in the side of thereservoir or holder in a convenient position, to be covered by the thumbor finger of the writer when it is desired to check the supply of ink tothe pen.

This tube passes up and down the whole length of the ink holder orreservoir, to prevent the ink from running out through it when laiddown, and terminates within the holder near the lower end.

a is the barrel or cylinder of metal. glass,

or porcelain, forming the ink holder or reservoir, closed at one end, atwhich the supply of ink is introduced by a screw-cap, b, and at theother by a curved spout or outlet, 0, having a minute orifice by whichthe ink is conveyed to the pen-nib d fixed in a suitable clip or holderon the end of the barrel 00. The

, spout c is bent up and terminates just beneath the inner surface ofthe nib, as shown. 6 is an air-tube of minute bore leading from aninlet-orifice, f, in the barrel a in such a position as to be readilycovered oruncovered by the fingers which holdthe pen in writing. Thetube 6 is bent double or U-shaped, and passes from the orifice f nearlyto the top of the barrel 4, andback again to its lower end,

the rate of flow being regulated by the admission of air through thetube 0, which, as before mentioned, has a very minute bore, throughwhich the air passes but slowly. The air, entering through this tube 6,displaces any ink that may be therein, and when it arrives at theextremity of the tube c it ascends in bubbles through the ink to the topend of reservoir.

Having thus described my invention, what I claim as new is 1. Afountain-pen holder closed at one end and having an outlet, 0, at theother for the ink, provided with U-shaped air-inlet tube of minute orcapillary bore passing up and down within the ink holder or reservoir,and terminating at one end Within the said holder or reservoir, and atthe other at an orifice in the side of the same in a positionto bereadily covered and uncovered by the fingers, substantially as hereinshown and described.

2. The combination of top-closed barrel a,

curved spout c, and U shaped air-tube c, having orifice f, as shown anddescribed, for the purpose set forth.

'3. The combination, with air-tube e, having orifice f, of the collar h,arranged to slide on the barrel, as and for the purpose specified.

The above specification of my invention signed by me this 11th da ofSeptember, 1876.
